Bell housing question

[Austingrace24]

Is the bell housing for an awd tranny and fwd tranny the same? Manual transmission. I haven't looked at any pics to see or anything.

Bell housing should be the same as in remove a motor from an auto and install with a manual. Awd and fwd differ because of the addition of the center differential. But both bolt to the same engine. Fwd flywheel is bigger then the awd. Clutch and pressure plate the same.

No, bell housing is not the same between the two.

How do I say...

Uh-NO.

I didnt think so I am just looking for a bell housing and checking all my options.

Your options are 1990-1994 AWD W5M33 5-speed transmissions. That's it.

The FWD and AWD bellhousings are completely different. As well, there are variations to the casting for the 90-94 vs. the 95-99 AWD bellhousings in relation to mounting points and mounting flange shape due to the difference in attachment points of the 1G 6b and 7b engine vs. the 2G 95-99 engine (1 extra mounting point). The mounting points are on the bellhousing for the front/rear mounts on a 95-99 while they are on the engine for 90-94 4G63's. Either way, you can use a 95-99 AWD bellhousing if you must, but you will simply have an extra bolt hole not being used on the bellhousing, and you will require a matching slave cylinder and use your standard 1G front/rear engine mounts attached to the block.

Personally, go find a 90-94 bellhousing. Cheaper and easier to find.

Keep in mind the bellhousings themselves are the same but the shifter is not and in my experience they aren't easy to change. Tim you may chime in here but I've tried like hell to get the lock pin out of a shifter and I couldnt' do it. I even cut a shaft off a scrap housing and put it on my 20 ton press and it wouldn't move. That being said if you can get it pick a bell housing that already has the year shifter you need.

The shift selector solid pin is an absolute bi*** to remove on most the transmissions I deal with. I have best luck with very precise hits from an air hammer with a punch tool attachment, then follow it up with a 3# sledge and 5/16" punch. The roll pin comes out way easier. If you don't use the right tools you will likely end up wrecking the shift selector assembly as well as wasting alot of time.

There are essentially two different shift levers installed on 1G bellhousings; 1989-1990 and 1991-1994. There are 2 different variations of shift selectors (short and long) which have matching shift rail ends. If you plan on using a 1991-1999 bellhousing to replace yours, you will have two options:

#1: Remove and swap the shift lever and shift selector assemblies from your old 1990 trans into the 1991-1992 bellhousing; using the 1990 lever with 1990 selector, and 1990 shift rails. These transmissions use a 2-hole 3/4 shift fork and only have a variation to the shift rail ends which will require the matching shift selector to be used. The short shift selector and matching rail ends were used until early 1991, so anything older will require the lever AND selector to be swapped. The early 1991 still has a different shift lever with a short selector, so the LEVER requires swapping.

#2: If a 1993-1999 bellhousing is used, then you will require all of your 1990 parts to be used (shift lever AND selector AND shift rails AND shift forks).
